Final answer:
The subject of this question is Mathematics and the correct answer is a) Optimization. Optimization involves finding the maximum or minimum value of a function, often using techniques such as differentiation.
Step-by-step explanation:
The subject of this question is Mathematics and it pertains to finding the minimum or maximum value of a function.
In this case, the correct answer is a) Optimization. Optimization involves finding the maximum or minimum value of a function, often subject to constraints or conditions. It can involve techniques such as differentiation and setting derivatives equal to zero.
For example, to find the maximum or minimum of a function, you can take the derivative of the function and set it equal to zero. Then, solve for the variables to determine the critical points and evaluate them to find the maximum or minimum values.
